Explanation:As in the above code, the first expression contains>operator whose associativity is left to right. Therefore the expression becomes ((a > b) > c), which becomes (0 > 2), so output is 0. And the second expression contains>operator whose associativity is left to right. Therefore...

On the other hand, right-to-left associativity pertains to the evaluation of operators from the right side of the expression to the left. An example of this is the assignment operator =, which has right-to-left associativity. Thus, in the expression a = b = c, the assignment is executed...
The operator precedence determines the order in which operations are performed in an expression. Operators with higher precedence are evaluated first.ExampleConsider the following expression:int x = 10 + 4 * 3; Here, the multiplication has higher precedence than addition, so 4 * 3 is evaluated ...
int a = 2, b = 3, c = 5; double f = 4.5; double res = a + b / f + c; In the last line of code, we can see that three variables are type int, and one is type double. According to the operator precedence, / will be the first evaluated; in this expression, b/f mean...
Operator associativity is thedirectionfrom which an expression is evaluated. For example, inta =1;intb =4;// a will be 4a = b; Take a look ata = 4;statement. The associativity of the=operator is from right to left. Hence, the value ofbis assigned toa, and not in the other directio...

↑The operand ofsizeofcannot be a C-style type cast: the expressionsizeof(int)*pis unambiguously interpreted as(sizeof(int))*p, but notsizeof((int)*p). ↑The expression in the middle of the conditional operator (between?and:) is parsed as if parenthesized: its precedence relative to?:is...
Operator associativity specifies whether, in an expression that contains multiple operators with the same precedence, an operand is grouped with the one on its left or the one on its right. Alternative spellings C++ specifies alternative spellings for some operators. In C, the alternative spelling...
